Diagnostic performance of and gene methylation versus α-fetoprotein in hepatocellular carcinoma.

Aim Of The Study: This study aimed to evaluate the methylation status of two genes in the peripheral blood as possible non-invasive biomarkers for hepatocellular carcinoma (HCC) development in Egyptian patients with hepatitis C virus (HCV)-related liver cirrhosis, compare them with α-fetoprotein (AFP), and assess their relationship with the clinicopathological characteristics of the tumor.

Material And Methods: Thirty healthy volunteers, forty patients with HCC on top of HCV-associated liver cirrhosis, and forty patients with HCV-associated liver cirrhosis participated in this study. Using methylation-specific polymerase chain reaction (MSP), the methylation status of and was assessed.

Design and synthesis of water soluble β-aminosulfone analogues of SCH 900229 as γ-secretase inhibitors.

In this paper we describe our strategy to improve the aqueous solubility of SCH 900229, a potent PS1-selective γ-secretase inhibitor for the treatment of Alzheimer's disease. Incorporation of ionizable amino groups into the side chain terminal generates water soluble β-aminosulfone analogues of SCH 900229 that maintain robust in vitro potency and in vivo efficacy.

Alternative core development around the tetracyclic indole class of HCV NS5A inhibitors.

Herein, we describe our research efforts to develop unique cores in molecules which function as HCV nonstructural protein 5A (NS5A) inhibitors. In particular, various fused tetracyclic cores were identified which showed genotype and mutant activities comparable to the indole-based tetracyclic core.
